Analyzing inequality in statistical capacity using World Bank’s Statistical Performance Indicators. High-income countries outperform low-income peers across all five pillars, with the largest gaps in data sources and infrastructure.
Published

November 23, 2025

Figure 1: Faceted line chart showing statistical performance gaps between high-income (teal) and low-income (purple) countries across five pillars from 2016 to 2023. Gray ribbons highlight the gaps between income groups. Data Sources shows the most significant gap at 43 points, followed by Data Infrastructure at 34 points and Data Services at 27 points. Data Use and Data Products show smaller gaps of 14 and 6 points, respectively. High-income countries consistently score higher across all pillars, with most gaps remaining stable or widening over time, except Data Products, which shows slight convergence.

11. Custom Functions Documentation

📦 Custom Helper Functions

This analysis uses custom functions from my personal module library for efficiency and consistency across projects.

Functions Used:

  • fonts.R: setup_fonts(), get_font_families() - Font management with showtext
  • social_icons.R: create_social_caption() - Generates formatted social media captions
  • image_utils.R: save_plot() - Consistent plot saving with naming conventions
  • base_theme.R: create_base_theme(), extend_weekly_theme(), get_theme_colors() - Custom ggplot2 themes

Why custom functions?
These utilities standardize theming, fonts, and output across all my data visualizations. The core analysis (data tidying and visualization logic) uses only standard tidyverse packages.

#### 11. Custom Functions Documentation

##### 📦 Custom Helper Functions

This analysis uses custom functions from my personal module library for efficiency and consistency across projects.

**Functions Used:**

-   **`fonts.R`**: `setup_fonts()`, `get_font_families()` - Font management with showtext
-   **`social_icons.R`**: `create_social_caption()` - Generates formatted social media captions
-   **`image_utils.R`**: `save_plot()` - Consistent plot saving with naming conventions
-   **`base_theme.R`**: `create_base_theme()`, `extend_weekly_theme()`, `get_theme_colors()` - Custom ggplot2 themes

**Why custom functions?**\
These utilities standardize theming, fonts, and output across all my data visualizations. The core analysis (data tidying and visualization logic) uses only standard tidyverse packages.

**Source Code:**\
